Long story short, I've come across an Imola E39 M5 for sale that is just begging me to bring it home.. and there's no way the misses will be on board with 2 shiny red sport sedans in one garage.
The ZHP is paid for, needs absolutely nothing and is a blast to drive on a daily basis. I went through the entire car shortly after I drove it back from San Antonio this passed winter and have loved every minute of it. Moreover, just a few months ago I sprung for Active Autowerke performance software with secondary air and post O2 functions deleted, Supersprint catless headers and a set of coilovers.
I've always wanted to own an M car, and I feel like the E39 M5 is the most attractive given that it's still a proper car with 4 doors ; ) and has the least amount of gut-wrenching failures as compared to say the E46 M3 or E6x M5/M6. I'm torn!!
